S-101 Update to Stakeholders

March 2010

Purpose• S-101 represents a major step forward in product

specifications for Electronic Navigational Charts.• This consists mainly of new feature types to

overcome existing issues (e.g. overuse of caution areas) and improved functionality leading to more efficient data handling.

• As a result, TSMAD is proposing a phased approach for the development , testing, and release of S-101*

*Approved TSMAD 19

S-101Software Development Lifecycle

• Planning– Phased Approach

• Analysis– Stakeholders Input

• Design– Test Beds

• Implementation• Maintenance

Benefits of a Phased Approach• Iterative Development

– Each iteration is usable and testable

• Controlled change– Enables a test of the change control process to both S-101 and S-100

• Enables smooth migration– Manageable change

• Will mitigate type approval concerns– Ensure that S-101 catalogues are not software or hardware updates

• Does not try and solve everything at once• Enables stakeholders to phase their development

implementation of S-100 based product specifications

Phases

Phase 1 S-57 ENC Content Equivalent

Phase 2 Enhanced Packaging and Data Loading

Phase 3 Extending the S-101 model

Phase 4 Scalability

Phase 1: S-57 ENC Content Equivalent

• S-101 draft 0.1 contains:– Feature Catalogue

• includes only those features and attributes that are currently in S-57 3.1.2

• XML– Portrayal

• Constrained by S-52 PL 3.4– General Feature Model– Includes the S-100 geometry

– Compound curves– Will contain updates - .001, .002 – Use of the new 8211 encoding

• Deliverable: S-101 .000 file and updates (no catalogue file)

Phase 1: Activities

• Feature Catalogue– Create XML Feature Catalogue– Create XSLT Style Sheet

• Information types will be utilized for the new 8211

• Begin developing Version 1 Data Capture and Classification Guide

• Develop draft 0.1 test dataset

Phase 1: Benefits

• Proof of Concept and validation of S-100– Feature Catalogue is exchanged as data

• Utilization of the new 8211 encoding• Creation of an S-100 compliant product

specification– Template for other S-100 product specifications

• Prove that an S-57 based product can be built using S-100

Phase 2: Enhanced Packaging and Data Loading Mechanisms

• S-101 draft 0.2 contains:– New support file formats and management– New file naming conventions– Populating exchange sets

• Metadata• Improved Display Scales for ECDIS loading

– Updating Scenarios– Includes text file updating

– Portrayal Catalogue is introduced• Deliverable: Complete Exchange Set including

updates

Phase 2: Activities

• Define new file formats (XHTML, JPEG etc.)• Define new naming convention• Create multiple test data sets utilizing the

enhanced display scales• Create enhanced updating scenarios• Enhance metadata and data discovery

Phase 2: Benefits• Demonstrate improved functionality of S-100• Prove that this process is supportable• Improved data delivery

– Improved data discovery– Easily Accessible Metadata– Support File Improvements (xhtml, jpeg)

• Continuous dialogue between IHO and stakeholders

• Opportunity to test potential efficiencies• Platform to demonstrate new capabilities

Phase 3: Extending the Model• S-101 draft 0.3 contains:

• Utilization of extended model capabilities– Introduce Complex attributes – Introduce Information Types– Multiple language support

• Explore the use of cartographic attributes for enhanced display

• Continue to update the Data Capture and Classification Guide to support enriched content

• Issue a new version of the Feature Catalogue and Portrayal Catalogue with content changes

• Deliverable: Phase 2 deliverables with extended content and updated Feature Catalogue and Portrayal Catalogue

Phase 3: Activities• Feature Catalogue

– Create XML Feature Catalogue– Include Complex attribute– Include Information type (enhanced language support)– Include Cartographic Attributes

• Portrayal Catalogue– Create XML Portrayal Catalogue

– Include updated portrayal to reflect extended feature catalogue– Utilize Add, Modify and Delete in the Portrayal Catalogue

• Deliverable: Complete Exchange Set, updated Feature and Portrayal Catalogues, Data Capture and Classification Guide

Phase 3: Benefits

• Prove maintainability– Feature Catalogue updating– Portrayal Catalogue updating

• Enhanced language support• Improved Update process• Prove that the catalogues are machine usable data• Data Quality and Usability improvements

– Complex attributes will clean underlying data

Phase 4: Scalability• S-101 draft 0.4 contains:

– Introduce the concept of Scale Independent and Scale Dependent Datasets

• Create an information object dataset that contains all the information objects for every dataset associated with it.

– Finalize Version 1 of the feature catalogue and portrayal catalogue

• Additional complex attributes• Additional information types

• Deliverable: Version 1.0 of S-101 Test Dataset and test datasets containing scale independent and scale dependent data

Phase 4: Activities

• Finalize Version 1 Feature Catalogue• Finalize Version 1 Portrayal Catalogue• Finalize Version 1 Data Capture and

Classification Guide• Creation of S-101 Version 1.0 Test dataset• Create Test Data containing scale independent

and scale dependent data.

Phase 4: Benefits

• Test the continued maintenance of the standard

• Improves the ability of data producers to reflect the real world– Caution Area Reduction
